Today is National UFO Day, and although Nevada and New Mexico come to mind most when you think of UFO's, Colorado has it's fair share of sightings too!
Each year, there are hundreds of UFO sightings, and many get reported to the National UFO Reporting Center (NUFORC). The organization has been around since 1974 and has a catalog of nearly 90,000 sightings. Along with offering a submission form so people can report their own UFO sighting, NUFORC also lists all the sightings they've collected by state.
Since the begging of 2019, there have been 34 UFO reports in Colorado. You can see a description of each here.
